WORCESTER — A Holden man who is an accomplished motocross rider was seriously injured when his motorcycle collided with an SUV on Lake Avenue Monday afternoon.

Police went to 28 Lake Ave. at 12:46 p.m. and found a 1987 Kawasaki motorcycle on the ground with extensive damage. A 2005 Cadillac Escalade at the scene had extensive front-end damage, police said.

Police said the motorcyclist, Joshua Kobel, 20, of Holden, suffered serious injuries and was taken to UMass Memorial Medical Center — University Campus. He was listed in critical condition this morning, according to the hospital.

The driver of the SUV was a 17-year-old Worcester resident who was not injured. Two passengers in the Escalade were uninjured, police said.

A Facebook page for Josh Kobel indicates he is a motocross rider who competes with the New England Hill Climbers Association. The group's website indicates he is in fourth place in the 450cc class and competed June 30 in Greenfield.

His Facebook page shows pictures of him clad in is his motocross attire and has links to videos of some of his runs, including a couple in which he crashed but appeared to recover quickly.

According to their preliminary investigation, police believe the motorcycle was traveling south on Lake Avenue when it stopped near Regatta Deli. Two other vehicles were in front of the motorcycle in the same lane. The lead car signaled to the Escalade driver to exit onto Lake Avenue.

The Escalade driver began to turn left onto the northbound lane of Lake Avenue. Meanwhile, the motorcyclist changed lanes, continuing to travel south on Lake Avenue. The two vehicles collided as the Escalade was turning left across Lake Avenue, police said.

Police closed Lake Avenue at the site of the crash for several hours to investigate.
